The Holy Grail of Value-First AI: Measuring Success

This article is Part 3 of our Value-First AI series. In Part 1,we introduced the Value-First AI Framework and argued that every AI use case must begin with a clear value hypothesis. In Part 2, we showed that even the best hypothesis fails without shared ownership – the business must have skin in the game. In this third part, we turn to the natural next question: once AI use cases are live, how do we actually measure success?

Everybody wants it, few have it

Bring up AI in any executive meeting and the discussion will quickly move beyond hype, pilots, and potential. After the initial excitement about what’s possible, the same question almost always emerges:

“But how do we know it works? How do we measure success?”

It’s a fair question. Leaders need proof that investments are paying off. But measuring the business value of AI is far more difficult than most expect. Everyone wants clear ROI numbers but few organizations manage to produce them.

Why? Because AI doesn’t operate in isolation. As we saw in Part 2, its impact depends on how it reshapes processes, people, and technology. That entanglement makes it nearly impossible to attribute results cleanly to “the model” alone.

Why measuring AI success is so difficult

The first difficulty is that AI never creates value on its own. It’s entangled with the workflows, people, and systems that surround it. A claims automation model, for instance, only delivers impact if employees actually use it, if the process adapts to faster case handling, and if downstream systems are ready to absorb the change. Measuring “just the model” gives a misleading picture, because the real effects depend on everything around it.

Even when adoption happens, the outcomes are rarely attributable to only AI. A drop in customer churn might coincide with rolling out a recommendation engine, but it might just as well be explained by new sales practices or improved customer service. In practice, multiple factors interact, making it difficult to draw a clean line from model to metric.

A third complication is that the gold standard of business impact measurement, the A/B test, is rarely practical. In digital products, experiments are straightforward. But once AI touches human workflows, control groups often don’t exist. It’s hard to imagine deliberately withholding an AI tool from half a call center team just to measure the difference.

Finally, measurement itself is resource-intensive. Building the instrumentation, running experiments, and tracking adoption at scale requires significant time and budget. In many cases, the cost of precise measurement comes close to, or even exceeds, the cost of building the solution in the first place. Leaders are left with a choice: invest in additional use cases and adoption, or in measurement that may provide clarity but slows over all progress.

Do we always need to measure?

This raises an uncomfortable but necessary question: is precise measurement always required? In some cases, the answer is no.

When AI is truly transformational, its effects are visible without the need for detailed ROI calculations. Employees notice that their daily work becomes faster or less error-prone. Customers experience quicker responses, more relevant offers, or smoother service interactions. Leaders see shifts in performance indicators across teams or business units that are too substantial to ignore.

In these situations, demanding exact financial attribution risks obscuring the obvious. The organization spends more time trying to pin down a number than it does realizing further benefits. Not everything that matters can be measured, and not everything that can be measured matters.

When measurement matters and when it doesn’t

Not all AI initiatives require the same level of proof. In some cases, the benefits are visible and broadly accepted. In others, the absence of hard evidence can stall progress entirely. Measurement, then, goes beyond numbers. It’s about building the trust and alignment needed to keep momentum.

There are moments when precise measurement is not optional. In these situations, data becomes the only way to move forward with confidence:

• ‍Measurement is critical when…
  
  • You need to convince skeptical stakeholders.
  • The investment is unusually large.
  • The use case is high-risk, high-reward, and still experimental.

But many initiatives don’t require the same level of scrutiny. When the value is already clear or the stakes are manageable, demanding exhaustive ROI figures can become more of a distraction than a help:

• ‍Measurement is less critical when…
  
  • Stakeholders are already aligned around a clear value hypothesis (Part 1).
  • The initiative is one of several manageable bets.
  • The transformation is obvious in how people work and how customers engage.

In these cases, what matters most is the discipline applied before launch: choosing the right use cases, aligning on expected value, and ensuring the business has skin in the game. When those elements are in place, the demand for detailed measurement after the fact is far less pressing.

The pragmatic path forward

Measuring AI success is often described as the holy grail: highly desired, rarely attained, and frequently expensive to chase. But the lesson from a value-first perspective is more practical. Organizations don’t always need a perfect ROI number to prove success. What they need is a disciplined approach across three dimensions.

First, a clear value hypothesis up front, so that everyone knows what the AI use case is meant to achieve (Part 1). Second, genuine business ownership, because value only emerges when processes, people, and systems adapt in line with the technology (Part 2). And third, a pragmatic stance on measurement: knowing when rigorous proof is required, and when visible impact in workflows, customer experiences, or aggregate performance is proof enough (Part 3).

The irony is that the strongest evidence of AI’s value often appears outside of dashboards. It’s felt in the way employees work, in how customers engage, and in how smoothly the business runs. Spreadsheets can help validate, but they rarely capture the full picture.

When you've done the hard work of defining value up front and ensuring the business shares ownership of outcomes, the measurement question becomes easier to answer. The transformation becomes visible in everyday operations, and the numbers follow naturally from the impact you've already created.
